Soil Organic Carbon (SOC)
Benchmark Value
Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.
Evidence & Context
The literature does not support a fixed percentage but defines a functional threshold linked to carbon saturation. When soils are pushed beyond their natural carbon storage capacity, the risk of increased nitrous oxide (N2O) emissions—a potent greenhouse gas—rises significantly.

Functional threshold beyond which SOC saturation leads to increased greenhouse gas emissions.
Scientific evidence from Australia State of the Environment 2021 report linking SOC saturation to increased N2O emissions.
